A couple of weeks ago a friend bought some Sennheiser 595’s and let me borrow them. They are open air phones. I run my audio through an AVR to use it as a digital switcher into my TACT preamp. I plugged the phones into the AVR. I played my favorite CD and it was a bit loud. I used the remote to lower the volume level of the AVR. A bit later it was still too loud and I lowered the volume level a bit more. I was blown away with the quality of the vocals. They were as fine, or finer, as I have ever heard! I took off the phones and noticed that my Salk HT1 speakers were still on. I turned them off and put the headphones back on. The phones were silent. I had lowered the AVR audio to inaudibility! I was listening to my own speakers!
That being said, the phones are very good and the bass is much superior to my TACT preamp and SVS sub combo. It will be interesting to see how my SoundScapes will compare in the bass.
